Prior to using the Refillable Cartridges, you must install your demo cartridges (the cartridges that originally came with the printer) in order to initialize the machine.

If your printer states that a cartridge is depleted, remove the cartridges, unplug the printer from the power and clean the chip on the cartridges with rubbing alcohol and a paper towel.

Plug the printer in, re-install the cartridges. The printer will ask if you're using Genuine HP cartridges select "NO" It will then ask if you want to continue printing click "OK" and the printer should continue printing without any errors.

All you have to do is remove the rubber plug on the top of the cart, inject ink until full, put the rubber plug back in place, reset the chip, and you are ready to go.
